Abstract
In a system for the transaction operation with terminal units connected to a central unit through the communication line, the transaction operation by use of an ineligible terminal unit is prevented. An illegality preventive information is provided for each terminal unit and stored in each terminal unit and the central unit. When the terminal unit transmits transaction data to the central unit, it also transmits the illegality preventive information registered in it. The central unit carries out the transaction process when the received illegality preventive information coincides with or has a certain relationship to the registered information.
